The Pro Breeze OmniCool 12,000 BTU portable air conditioner is built around one priority: quiet. At just 55 dB, around the level of gentle rainfall, it is the quietest air conditioner in the Pro Breeze range, so you can cool a room without the intrusive drone that puts many people off portable AC. With 12,000 BTU of cooling and the rule of thumb of roughly 600 BTU per square metre, it is well matched to medium-sized rooms up to around 20m², including bedrooms where its low noise is a genuine advantage overnight. It is a true 3-in-1 unit, switching between cooling, fan and dehumidifier modes, with a dedicated sleep mode that adjusts gradually through the night to keep you comfortable. Smart Wi-Fi app control lets you start it remotely so the room is already cool when you walk in, then set a temperature and let it manage itself. As with every monobloc portable air conditioner, it is not hoseless: the included exhaust hose and window kit vent hot air outside, which is what makes the cooling possible. At 33 kg with a supplied window kit, it installs at the window and stays put for the season.

OmniCool™ 12,000 BTU 3-in-1 Ultra-Quiet Portable Air Conditioner with Dehumidification Function - Smart Wifi App — FAQs
Is the OmniCool quiet enough for a bedroom?
Yes. At 55 dB, around the level of gentle rainfall, it is the quietest air conditioner in the Pro Breeze range and is well suited to bedroom use, with a sleep mode that adjusts gradually overnight.
What room size does 12,000 BTU cool?
At roughly 600 BTU per square metre, the 12,000 BTU output suits medium-sized rooms up to around 20m².
Does the OmniCool need venting out of a window?
Yes. It is a monobloc unit and must vent hot air outside. The exhaust hose and window kit are included; it is not a hoseless air conditioner and cannot cool without venting.
What is the difference between 12,000 BTU and a higher 14,000 BTU unit?
More BTU means more cooling capacity for larger spaces. The 12,000 BTU OmniCool suits rooms up to around 20m², while a 14,000 BTU model covers larger rooms up to around 23m².
Can I control it from my phone?
Yes. It has a smart Wi-Fi app so you can switch it on, set the temperature and change modes remotely, and have the room cool before you arrive.
